BACKGROUND Technical Field

The embodiments herein generally relate to reducing several unicast streams corresponding to a common OTT non-linear content in a communication network by incorporating one to many networks, and more particularly, reducing traffic load in a Content delivery platform, cellular core network and a radio access network.

Description of the Related Art

Consumers of streaming media content receive a content from their content providers through a one-to-one delivery method. The content is unicasted to a user device. This method of delivery employs a lot of bandwidth and for managing the dynamic demands for a streaming media content, the ISPs have providers must employ elastic Content Delivery Networks (CDN).

More specifically, when the demand for streaming media content is high, cost directly goes up as the number of users rises, even though they may be consuming a common content. This is because traditional methods use unicast delivery where each user receives an individual stream. This leads to inefficient utilization of bandwidth. Bandwidth requirement can explode when demand is high leading to network congestion.

Further, at any point in time, there is a plurality of users who view the same streaming media content. For all these users, the same content is replicated in the CDNs in order to facilitate the one-to-one transmission stream which is traditionally employed. This results in an in-effective usage of bandwidth because multiple copies of the same data are created and transmitted in parallel to multiple user devices at the same point in time. Also, the CDN must handle multiple sessions for the same content.

In real-time, there always remains sets of users who view the same streaming media content at the same time, for whom the transmission stream to the user device remains the same. This type of linear content can be broadcasted efficiently to all users. In a typical non-linear content delivery system, even though the number of users is consuming the same content, there may be a finite time difference between the start of viewing instance among them. So, by simply shifting the content to broadcast may not work, unlike the case of live-streamed content.

Accordingly, there is a need for mitigating and/or overcoming drawbacks associated with current systems and methods.

SUMMARY

In view of the foregoing, embodiments herein provide a system for switching at least one User Equipment (UE) from a unicast mode to a broadcast or multicast mode to transmit a streaming media content to the at least one User Equipment (UE).

In some embodiments, the unicast cache database 808 stores the caches corresponding to the unicast mode. In some embodiments, the broadcast/multicast cache database 810 stores the caches corresponding to the broadcast or the multicast mode. In some embodiments, the processing engine 806 identifies a keyframe in the caches corresponding to the broadcast or the multicast mode at which processing and rendering are switched from the unicast mode to the broadcast or the multicast mode.
